MSI. Based on my limited experience, they are very well made reliable stable boards. I am quite happy with my 2 6309's and my K7T Turbo non raid. My 6309's have been overclocked since they were built and have really worked well. My K7T Turbo runs an 850 Duron at default, but has been impressive in its performance. (Well, at least to me

) While I have no personal experience with ECS, I have looked at them and been tempted by their very attractive prices, but the old adage "you get what you pay for" keeps me from trying one. And unfortunately, I am a creature of habit (witness the two 6309 systems), if something works well for me, I tend to stick with it. When I did decide to venture out and build an AMD system, MSI was the only board I considered based on my previous experiences with the 6309's. I have not been disappointed with the K7T Turbo's performance. I am even considering yet another version of the 6309, the 694T to use with my 900 Celeron processor and resurrect my old PIII 600E for the older of the two boards to put together a "work only" system for my wife to use, while my 3 boys and I play games and surf on the little 3 system home network.
